They are used as an important component to complete a variety of circuits, such as decoupling and bypass, switching power supply, automation systems, energy converters, and high-end measurement systems.In military applications, these capacitors are used in robust systems to provide high capacitance and low ESR, in order to achieve reliable operation in harsh conditions. In medical applications, these capacitors are used in pacemakers and defibrillators, where high reliability and low ESR are critical to the functionality of the device. In automotive applications, these capacitors are used for temperature stability and EMI/RFI suppression, as well as for capacitor bank applications in alternators and starters. In consumer applications, these capacitors are used in computers, Radio Frequency Identification (RFID) systems, and portable electronic devices such as mobile phones and MP3 players. In telecommunication applications, these capacitors are used in batteries, switches, base stations, and power supplies, for respectively energy storage, signal switching, transmission line protection, and DC/DC conversion. Finally, in aerospace applications, these capacitors are employed in avionics systems, such as aircraft and spacecraft, for reliable capacitor bank designs in amplitude, phase and frequency control circuits.

Working Principle

A tantalum capacitor is composed of two electrodes, commonly called the anode and cathode. The anode is usually made out of pure tantalum powder and the cathode is made out of manganese dioxide or conducting polymer. An electrolyte, such as manganese acetate, is sandwiched between the two electrodes and serves as the dielectric. When a voltage is applied across the two electrodes, it causes current to flow through the electrolyte. This creates an electric field inside the electrolyte, which results in the formation of a charge storage layer, known as the Helmholtz double layer. This double layer of charge carriers (ions & electrons) stores energy in the form of electrical potential, which makes up the capacitance. The amount of capacitance is determined by the capacitance of the electrodes, the thickness of the electrolyte, and the surface area of the electrodes. The ESR of a tantalum capacitor is determined by the equivalent series resistance of the electrolyte. The higher the electrolyte\'s ESR, the higher the capacitor\'s ESR will be. The temperature stability of a tantalum capacitor is determined by the stability of the anode. The anode has a low temperature coefficient, meaning that the capacitance value does not change greatly as temperature changes.

Conclusion

T495X227M010ZTE050 tantalum capacitors offer excellent reliability and performance, even in harsh environmental conditions, and are widely used in a variety of different industries and applications. These capacitors have high capacitance, low ESR, and temperature stability. They are mostly used in military, medical, automotive, consumer, telecommunications and aerospace applications. The working principle of the tantalum capacitor is based on the Helmholtz double layer of charge carriers that store energy in the form of electrical potential.
